| titleOfInvention | Precast dry material sprayed concrete |
| abstract | The invention discloses a prefabricated dry-mixed shotcrete, which belongs to the technical field of building materials, and the technical scheme is characterized by comprising the following components in parts by weight: cement, pebbles, medium sand, a high-efficiency setting accelerator, a binder and a water reducing agent; the cement is P.O42.5-grade ordinary portland cement; the adhesive comprises attapulgite, sodium silicate and potash water glass, and the weight ratio of the attapulgite to the sodium silicate to the potash water glass is 2:1: 1. By reasonably controlling the ash-to-bone ratio and the sand rate, the invention can improve the strength and compactness of concrete, reduce dust pollution and reduce the rebound rate; through the attapulgite, the sodium silicate and the potash water glass, the dryness of the dry-mixed compound can be improved, the adhesive force and the viscosity of the sprayed dry-mixed compound can be improved, the rebound rate can be reduced, and in addition, the sodium silicate and the potash water glass have good heat resistance and can improve the heat resistance of concrete. |
